I The present invention relates to mechanical hay rakes and "it consistsin the combinations, constructions anclarrangements of parts hereindescribed. and. claimed.

It isan object of the present invention to provide a mechanical hay rakewhich is self-actuating its forward "movement ever the ground withoutthe necessity of a power takeoff from the supporting wheels usuallyassociated with mechanical hay rakes.

-Another object of the invent n is thepro: vision of a noveiarrangemtines upon an endless chainforining a' pa 'e invention.

Kh'ther object or the invention is the provisfo'h of novel and simple"means ffor raising :and Iii ering the operable parts are mechanical nayfake with-respecttothegrouii A further object'offithe invmtien is theprovisionof a guard for guiding the hay and at the. same-time-preventingit from passing between the moving partsof'theme'chahi'sm.

Another object of the invention is the provision of a novel lbracingmeans for the tines of a mechanical hay rake.

A still further object of the invention is the provision of a novelendless chain construction having spaced tines thereon.

Other and further objects of the invention will become apparent from areading of the following specification taken in conjunction with thedrawings, in which:

Figure 1 is a plan view of an embodiment of the invention,

Figure 2 is a perspective view of a portion of the apparatus shown inFigure 1,

Figure 3 is a side elevational view of the mechanism shown in Figure 1,

Figure 4 is a sectional view taken along line 4-4 of Figure 3,

Figure 5 is a sectional view taken along line 5-'5 of Figure 3,

Figure 6 is an enlarged sectional view taken along line 66 of Figure 1,V

Figure '7 is a sectional view taken along line '|--'I of Figure 6, and

Figure 8 is an enlarged fragmentary perspective view showing certainelements of the invention.

Generally there is provided a mechanical rake having a frame supportedupon a pair of wheels and having vertically dependent therefrom at a 45degree angle to the longitudinal axis of the frame an endless chainmounted upon four sprockets and having a plurality of outwardlyextending tines so shaped as to extend slightly '1 claim; 7 (01. 56-376) the direction of the motion of the mechanism over the ground whenin contact therewith. The

tines engaging the ground will cause a continuous movement of the chainrearwardly at an angle to the direction of motion of the machine overthe ground, thereby delivering hay to one side of-the machine, Noconnection is necessary with the supporting wheels of the frame toimpart motion to the chain and its attached tines. Provision is made forraising and lowering the chain with respect to the ground and a guard,prefer'ably of sheet metal, is positioned within the area encompassedby'the chain. 4

Referring more particularly to the drawings, there is shown therein amechanical rake comprising a substantially triangular frame Ill, attheforward. or apex end of which is pivotally connected a tongue II, asindicated at 12. The tongue is provided with a rearwardly extendingportion 13 adjacent the rear end of which is journaled the lower endof-a vertically extending shaft H, the upper end of which is threadablymounted in a collar l to which is affixed an operating handle I6. Theshaft 14 extends through a cross member I] carried by the frame [0. Acompression spring 18 is interposed between the cross member I! and theportion I3.

To the frame i0 is welded or otherwise affixed a flat guard member 26which extends vertically downwardly therefrom and whose plane forms arearwardly extending angle of approximately 45 degrees with thelongitudinal axis of the machine,

The guard 20 presents a substantially vertical front edge 2| and a rearedge 22 which extends upwardly and outwardly. The top and bottom edgesare substantially parallel with the ground.

At each corner of the guard 20, there is mounted a sprocket 23, 24, 25and 26, respectively, over which is trained an endless chain 21, eachalternate link of which is provided with an outwardly extending tine 28,each of which is curved slightly in a forward direction when positionedat the bottom of the guard 20, that is to say, between the sprockets 24and 25. The guard is affixed to the frame ID by brackets 29.

A guide rail is affixed adjacent the front end of the guard 20 by abracket 3! and extends along the forward and lower edges of the guard 20in spaced relation thereto and inwardly of the outer extremities of thetines 28 and is also supported by a bracket 32 adjacent the rear of theguard the frame extend rearwardly and downwardly to form legs 34 and. 35to which are centrally and pivotally connected, respectively, the arms36 and 31 of a U-shaped member 38 which has centrally mounted thereon anupwardly extending dog 39 having an opening 40 therein.

A shaft 41 is provided with an integrally formed hook 42 at its lowerend, which is adapted to engage in the opening 40 and extends upwardlythrough a journal 43 formed centrally in the bar 33 and is threadablyengaged in a collar 44 to which is affixed a handle 45.

To the rearmost ends of the U-shaped mem-- ber 38 there is revolubly'mounted supporting wheels 46 and 41 and a brace bar 48 interconnects thearm 31 and a point adjacent the forward end of the guard 20.

In operation, it will be apparent that the draw bar Il may be attachedto a tractor or the like for moving the same over the ground and thatthe tines 28 adjacent the ground may be adjusted in position withrespect to the ground by manipulating the handles I6 and 45 which willraise or lower the forward and rearward ends, respective-- ly, of theframe ill.

.The machine is then moved over the ground and the tines will engage theground and be forced to move rearwardly and to one side in a rakingmovement, thus causing hay which may be in its path to be moved to oneside of the machine. The guard 20 prevents any hay from While but oneform of the invention has been shown and described herein, it will bereadily apparent to those skilled in the art that many minormodifications may be made herein without departing from the spirit ofthe invention or the scope of the appended claim. j What is claimed is:

An apparatus of the character described comprising a frame, a flat metalguard member ver- Eically dependent from the frame at an angle o thelongitudinal axis thereof, sprockets revolubly mounted at each corner ofthe guard mem- 'ber, a chain trained over said sprockets, tinesoutwardly disposed on said chain, a rearwardly extending bracing rodinterconnecting the frame "and the guard member, a guide rail carried by'said guard member in spaced relation thereto and adjacent the rearfaces of the lowermost escaping the raking movement by passing over offoreign matter. It will also be noted that that part of the chain 2'!which is adapted to move upwardly, that is to say, theportion thereofbetween the sprockets 25 and 26, extends upwardly and outwardly so thathay will fall therefrom by gravity at the end of the raking operation.
